Good point! What specifically do you think the crystals/minerals are affecting? Just curious. You’ve had a lot of experience. You must have some ideas, yes? Same question for the metallurgy.I am not a scientist...
I only know that all the different electrical wires of my house coming from the principal external electrical cable from my central electrical panel are ONE connected grid, where all that is connected add some noise of his own...Minerals and crystals added to the grid decrease the noise level of the electrical grid....The minerals act like a filter, each one differently, disturbing or improving the audio signal through a filtering of the noise level of the electrical energy field...
